Columbia University Medical Center no longer provides Aetna with
your Social Security Number for identification purposes. In lieu of this, your Columbia Personal
ID number is used. Your Columbia University ID number begins with a C and is followed by 9
digits. It can be found by logging in at http://ssol.columbia.edu/
with your Uni.

Enter Aetna Navigator by replacing the ´C´ in your C number with a 3. Use this
modified number (10 digits) to register. You can then print a temporary insurance card, check on claims
processing and access other valuable health information.

Please note, your Aetna Health Insurance ID Card will not include your Columbia University ID
Number. Rather, for privacy purposes, it will include a randomly assigned number (which begins
with a ´W´). If you are a returning student, your ´W´ number will remain
the same as prior years.

If you need to fill a prescription and do not have your card, the pharmacist can verify
coverage if you know either the ´C´ number with the ´C´ replaced by 3, or
the ´W´ number generated by Aetna.
